Aston Martin’s first motorcycle is finally here after a painfully long wait. The AMB 100 is the result of a collaboration between automaker Aston Martin and legendary motorcycle company Brough Superiior. The limited-production bike is primarily a track-focused moto, and its powered by a supercharged Brough Superior V-twin engine with 183 horsepower and a mere 408-lb dry weight. While that’s a bit less than the BMW S 1000 RR’s 205, it’s easily more than enough to slam your kidneys and soil your undies. The hulking speed machine is limited to 100 units, of which 90 have already been spoken for.
